Each of these bluetooth tracker tags is linked to a phone app and attaches to nearly anything, so your phone will help you track it down. Stick one on your dog collar, your keys, your backpack, and pretty much anything else you lose track of. And if you lose your phone, you can double-click the button on a tag, and it'll make it ring so you can find it.
